I think some people would ask the same question about sport/trad/mountaineering/hill walking/ice climbing/climbing in general....no? it's fun, who cares? I tie in, I boulder, I even used to hill climb, such famous and arduous climbs like mt. baker, mt. persus in winter (at least grade VI, 5.16d, snow walking grade 9) and barring peak. WHAT WHAT! troll
